Answer:
A =
. r^2
If A = 9
ft^2
. r^2 = 9
ft^2
r^2 = 9ft^2
r = sqrt(9ft^2)
r = 3ft ( r>0)
Step-by-step explanation:
If there's a plus sign in between the 2w and 3 then the answer is C. w 5.5
C=2pir
r=4
c=2pi4
c=8pi
aprox pi=3.14
c=25.12
Answer:
First one is wrong. x should be 16.
Second one is not completely visible, so cannot say.
Step-by-step explanation:
In the last step, the divison by 4 yields:
x/16 = 1, so x = 16
